HUB-ATTACHING DEVICE.

SPECIFICATION formingpart of Letters Patent No. 260,811, dated July 11,18S-2.

Application filed April 13, ISEQ.

To all whom it may concern Beit known that I, AUGUST Where, a citizenot' the United States ot' America, residing at Galveston, in the countyof Galveston and State of Texas, have invented certain new and usefulImprovements in Hub Attaching Devices 5 and I do hereby declare thefollowing to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art to which it appertaius tomake and use the same.

This invention has relation to hub-attaching devices, and is designed asan improvement on the devices shown and described in Letters Patent ofthe United States of America grained to me November 22, 1881, No.249,809.

Theseimprovements are designed to provide better and additionalfastening means for securing the axle-box to the spindle.

My improvements consist in a metallic anuulus formed or provided withrearward-extending bolts.

Myimprovements further consist in the combination, with an axle-boxformed with an annular shoulder at the base oi' the fins and a pluralityot' longitudinal grooves iu the perimeter, of a metallic annnlusadaptcdto the shoulder in the axle-box, and formed or provided with a.plurality ot' rearward-extendingbolts, for the purposes hereinafter setforth.

Myimprovements further consist in an axlebox formed with an annularshoulder at the base ot' the ns and a plurality of grooves in itsperimeter, in combination with an annulus adapted to the shoulder in theaxle-box, and formed or provided with rearward-extending bolts and nutsfitting in the grooves ofthe axlebox, and an abutting cap or ring, ashereinafter set forth.

My improvements also consist in the novel construction and combinationof parts, as will be hereinafter set forth.

In the accompanying drawings, making a part of this specification,Figure l is a longitudinal sectional view. Fig. 2 is a perspective viewot' the annulus, with bolts and fastening means. Fig. 3 is a view of thecap with ange to t over the end of the axle-box, and Fig. et is an endview of the axle-box. Fig. 5 is a perspective view of cap F, and Fig. 6is a detached view of end nut.

(No model.)

`| The letter A represents the end of an axle with an annular flange, c,circular bearingj",A f

and wrench-grip space for screwing in place on the spindle or whileremoving it. The annular flange of this sleeve tits in the open end ofthe axle-box, and the bearing f corresponds with the opening in the ringwhich is screwed over the face ofthe box. These parts are herein set outand described as being common with my improved hub-attachin g devicedescribed in my Letters Patent hereinbefore mentioned.

TheletterUrepresents the axle-box, provided at the outer end withinternal screw-threads, and in interior conformation corresponds to theforni of the spindle, and the tapering portion made somewhat longer thanthe tapering portion ofthe spindle. This axle-box is also formed with anannular shoulder, D, at the base of the tins, andhasthewallagainstwhichtheannnlns, hereinafter described, sets at or nearly at right angles tothe shoulder, and in the perimeter of the body Vand annular wall t' otthe axle-box are formed a plurality of semicircular grooves 7c for thepurpose of receiving the bolts ofthe ring or annulus, as hereinafterdescribed.

The letter E represents a metallic ring or annulus, which lits over theshoulder on the axleboX at the base of the tins, and is provided withcurved extending boltsm, having screwthreads and nuts on the ends, andiits in the semicircular grooves in the box and extends through thebolt-holes in the abutting cap, substantially as seen in Figs. 1 and 3ofthe drawings.

The letter F represents the abutting cap or ring, with a centralcircular opening, n, fitting about the bearingf, and formed with ahorizontal wall, n', adapted to tit over the end ot' the axle-box, andby means of the bolt-holes through it, which correspond to the bolts ofthe ring on the spindle, it is secured to the face and over the end ofthe axle-box, as shown in Fig. lof the drawings. Between the inner faceot' the ring F and the face of the screw-threaded sleeve and dan ge ofthe axle-box a leather washer or rubber ring is fixed, for the purposeof obviating rattling ofthe parts when in mo tion. At the outer endofthe axle-box, fitting the screw-threads of the same, is the hollow nutor chambered cap G,wl1iel1 does not quite reach the end of spindle, andin the center of this nut is a perforation, with a screw, p, inserted.The chamber r in this cap is for the purpose ot' holding the luhricator,and the oentral perforation with screw therein is intended to alt'ordready and quick means l'or introducing and preventing waste of thelubricating material.

To apply my improvementsin use tl1escrew` threaded sleeve is put in itsplace in the open end ofthe axle-box, the annulus or ring being in placeon the shoulder at the base or" the lins, with its bolts set in thelongitudinal grooves, after which the abutting cap is adjusted on thebolts, the intervening washer having been inserted, and then screwedhome and secured by the nuts ou the bolts. The wheel is put on over thespindle and the screw-threaded sleeve screwed thereon.

What I claim as my invention, and desire to l secure by Letters Patent,is-

l. A metallic ring adapted to `be adjusted around a shoulder on theaxle-box, formed or provided with a plurality of rearward-extendingbolts, substantially as described.

2. An axle hoX formed with an annular shoulder at the rear ofthe tinsand a plurality of longitudinal grooves, in combination with a metallicring adapted to set around said shoulder, and formed or provided with aplurality of rearward extending bolts with fastening means,substantially as described.

3. The eolnbinatioinwith an axle-box formed with an annular shoulder atthe hase of the tins and rearward-extending longitudinal grooves, of ametallic ring provided with a plurality ot' curved bolts, and anabutting cap iitting over the end ot' the axle-box and secured againstthe same, substantially as set forth.

4. The eombination,witl1 an axle-box formed with an annular shoulder atthe base ofthe lns and rearward-extending longitudinal grooves,

ot' a metallic ring provided with a plurality ot' curved bolts, anabutting ca p fitting over the end of the axle-box and secured againstthe same, and a screw-threaded sleeve, substantially as described.

5. The combinatiomwith solidspindleformed substantially as described,ot' the axle-box C, having the shoulder D and longitudinal grooves k,the ring E, having the bolts m, the abutting cap F, and screw-threadedsleeve B, substantially as described.

In testimony whereof l affix my signature in presence of two witnesses.

AUGUST WARTH.
